<dd><p>Bases: <code class="xref py py-class docutils literal notranslate"><span class="pre">Registry</span></code></p>
<p>An implementation of the <code class="xref py py-class docutils literal notranslate"><span class="pre">Registry</span></code> interface
that uses etcd as a distributed key-value store for service discovery.</p>
<p>Nodes register themselves with their connection information and metadata.
The registry uses leases to automatically deregister nodes if they fail
to refresh their lease, providing a degree of fault tolerance.
Node information is signed to ensure integrity and authenticity, although
the current signature verification logic in <cite>__verify_signature</cite> appears
to verify a signature it just created, rather than a signature from a remote node.</p>
